Originally posted by WJW Since I don't think any digital has a match needle exposure system it sounds like you are looking for an inexpensive K-mount film camera. Here are a few suggestions that might be found for under $50 shipped on ebay (usually with lenses):
Chinon: CG-5 (AW), CM-4, CM-5
Ricoh: XR-1 (AW), XR-2 (AW), KR-5 Super, KR-5 III,KR-5 Super II, XR-10 (AW), KR-10
Sears: KS-1000 (AW, same as XR-1), KSX
AW= Window
My favorites from the list is the XR-1 and CG-5 since they both have DOF preview levers and flip up the mirror at the start of the self-timer. The XR is completely mechanical and only uses battery power for the meter. I currently have an XR-1 and use it with a K/M42 adapter for my M42 lenses.
A couple of comments
All Pentax DSLRs have matched needle metering, when you use them in manual, with automatic apature lenses, and manual lenses by using the DOF prevview.
You forgot the XR-2s which will do full manual and also apature priority auto exposure, it differes from the XR-2 by accepting a motor winder at 2 FPS
Also as noted earlier the KX has matched needle metering, in fact it is identical to the XR-2s except for the color of the shutter speed indicator.
